         4 . The liquid crystal panel according to  claim 1 ,
 wherein the structure is a plurality of members scattered around the seal part and each having a columnar or spherical shape.   
     
     
         5 . The liquid crystal panel according to  claim 4  further comprising
 a plurality of spacers arranged in an outer region of the seal part between the substrates to be spaced apart from one another, 
 wherein the structure is a component of the same type as a type of the spacer. 
 
     
     
         6 . The liquid crystal panel according to  claim 1  further comprising
 a light shielding film arranged to spread along an inner side of the second substrate and having a hole formed therein. 
 
     
     
         7 . The liquid crystal panel according to  claim 1  further comprising
 a display panel arranged on an outer side of the structure and using an organic EL light emitting diode or a micro light emitting diode. 
 
     
     
         8 . The liquid crystal panel according to  claim 1 ,
 wherein the liquid crystal is polymer dispersed liquid crystal.   
     
     
         9 . The liquid crystal panel according to  claim 1 ,
